What boolit diameter for new Marlin 1894 .45 Colt

[Gray Fox]

I'm doing a good deal for a NIB Marlin 1894 in .45 Colt. My two favorites for this are the Lee 255 RNFP and the 300 RNFP GC. Can any of you suggest the most accurate boolit diameter for this rifle? As cast both normally fall at .454 from WD WW. My usual loads for them in a Rossi .45 Colt are 8.0 of 231 for the 255, which also shoots well in my Smith 25-5, and 22.0 grains of H110/296 for the 300, both sized to .452. Thanks for any insight.

I have three Marlin 1894 Cowboys in .45 Colt, and they all like bullets sized .452".

Hope this helps.

Fred: Thanks for the experienced reply. .452 is what I'd hoped for as that is what my two Rossi .45s like. Now I've got to get a set of Skinner sights ordered. GF
